SPRING-MATTRESS SUPPORT.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed July 22, 1920. Serial No. 398,076.

'To all whom it may concern:

Be it known that I, HARRY LITVAK, subject of the Government of Russia, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Spring-Mattress Supports, of which the following is a specification.

This invention relates to spring mattress supports. One of the objects thereof is to provide an article of manufacture of this type in which the bed stead and spring together shall be foldable into small compass.

Another object of this invention is to provide a combination bed stead and bed spring in which the latter may readily be removed from the former and the former made collapsible so that the combined device may be readily disassembled o put together as desired.

A further object is to provide a combined bed stead and bed spring having among others the foregoing features and which shall be Well adapted to meet the conditions of hard practical use.

Other objects will be in part obvious and in part hereinafter pointed out.

Certain features herein shown and described are shown, described and claimed in my co-pending application Serial No. 396,686 filed in the United States Patent Office July 16th, 1920, and accordingly are not claimed herein.

With the above exception, the invention accordingly consists in the features of. construction, combinations of elements and arrangement of parts which will be exemplified in the apparatus hereinafter described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings in which is shown one of various possible illustrative embodiments of this invention,

Figure 1 is a plan view of an embodiment of this invention showing the collapsible bed stead and the bed spring in place thereon;

Fig. 2 is a cross-sectional view on line 22 of Fig. 1; and

Fig. 3 is a partial detailed view of a side rail of the bed stead in section.

Referring in detail to the drawing, the end-rails of the bed are of two part construction consisting each of a pair of channel members 10, 10 and 11, 11 respectively hinged together as by means of hinges 12,

12. The side rails of the bed stead are also of two part construction, each part comprising a plurality of separate tubular sections 13, 13 18 The extreme tubular sections 13 of each part are secured in any suitable manner to the end rails. The members 13, 13 are held end to end on a solid core member 15 which extends substantially the length of the several sections of the part and may be secured in any suitable manner to the extreme outer section 13 In the form shown in the drawing, the sections 13 are provided with a perforation 16 adapted to register with a hole 17 formed in the core member and a pin 18 passed through the tubular section of the core, thus holding the sections together, as will be readily understood.

The two parts of the side rails are joined together by means affording a longitudinal adjustment of the side rails to provide for various lengths thereof. To this end turn buckles 19 are provided having screw bolts 20, 20, one of said bolts having a right hand thread and the other a left hand thread. These turn buckles bridge the two parts of the side rails and are secured thereto by means such as hooks 21 extending from the end of the core 15 as clearly appears from Fig. 3 of the drawing.

The bed spring comprises a spring body of the usual net work construction divided longitudinally into two halves 22, 22 secured to two-part supporting and attaching members 23, 23 and 24:, 24 hinged together by means of hinges 25, 25. The halves of the spring body are also hinged to each other by means of hinges 26 so that the spring may be foldable with the bed stead as will be readily understood. To provide for adjustment of the tension in the spring body, the end attaching members 23, 23' and 24, 24 are provided with turn buckles 27, 27 similar to turn buckles 19. These turn buckles 27 27' serve at the same time as the means for attaching the spring to the bed 100 stead as will be readily understood.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that 105 all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

It will thus be seen that there is provided 110 apparatus in which the several objects of this invention are achieved and which is well adapted to meet the most severe conditions of hard practical use.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent v A spring mattress support comprising a spring receiving frame and a bed spring therefor, said frame comprising two part hinged end rails and longitudinally adjustable side rails secured thereto; said spring comprising two longitudinallyv hinged sections secured to two part hinged end attaching members, and means for detachably securing the latter to said end rails in parallel relation thereto whereby said end rails, spring sections and attaching members may be folded together, said means serving also to adjust the tension in said spring sections.

Signed at New York city, in the county of New York and State of New York, this 23rd day of June, A; D. 1920. r
